They reviewed German energy & heating systems, a hydrogen powered car, visited a hybrid power plant and a community in Feldheim that generates more power than they consume. The Feldheim community has a combination of a biogas plant, solar panels and a wind farm. The Brandenburg area that was visited produces 60% of their energy from renewable sources.

Both Minnesota and Iowa are already leaders in renewable energy with Iowa generating 20% of the state’s energy from wind and began their renewables effort in the 1980’s. Minnesota has a considerable number of wind farms in the south regions of the state that have been growing at a rapid rate.
